Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747424, here are decompositions:
- 5 + 8747419 = 8747424
- 17 + 8747407 = 8747424
- 43 + 8747381 = 8747424
- 97 + 8747327 = 8747424
- 151 + 8747273 = 8747424
- 163 + 8747261 = 8747424
- 167 + 8747257 = 8747424
- 173 + 8747251 = 8747424
Showing the first eight; more decompositions exist.
